Description
Technical Field
[0001] This invention relates to the technical field of orthopedic medical devices, specifically to a bone channel guide and its usage method. Background Technology
[0002] In orthopedic surgery, after drilling a bone tunnel along the radial direction of the bone, it is necessary to insert a fixation suture into the bone tunnel. This requires a suture guide to guide the suture through the bone tunnel, that is, to guide the traction suture from one end of the bone tunnel to the other side, so that the soft fixation suture passes through the bone tunnel.
[0003] In actual surgical procedures, when treating fracture patients, after aligning the bone fragments, it is necessary to fix the bone. In some fracture treatments, it is necessary to drill bone tunnels on both sides of the fracture site, and then use a suture device to pass fixation sutures through the two bone tunnels for fixation.
[0004] Existing suture guides generally consist of two hinged suture tubes and a hook rod. The suture is threaded through the suture tube, and a hook head is provided on the hook rod. The suture tube is inserted into one of the bone holes, and the hook rod is used to hook the suture and pull it out of the bone passage. However, this method has two problems: first, the hook is not secure and is easy to slip; second, it cannot effectively thread the suture through two bone holes that are not on the same line, or it can only assist other instruments in suture guiding, resulting in poor applicability. Summary of the Invention
[0005] This application proposes a bone tunnel suture guide that can be used for threading sutures through various asymmetrical bone holes, and the suture is threaded by positioning and pushing, making it more convenient to use.
[0006] Therefore, the technical solution adopted in this application is as follows: a bone channel guide, including a gripping part, and further including: a tube, installed on the gripping part, for threading a guide assembly; a bone channel tube, connected to the lower end of the tube, for threading the guide into a first bone channel during guide insertion; a bone channel guiding and docking mechanism, disposed at the lower end of the bone channel tube, for automatically docking with a second bone channel after the bone channel tube enters the first bone channel; and a pushing mechanism, disposed at the lower end of the bone channel tube, for pushing the guide assembly to push the guide out from the second bone channel. By adopting the above technical solution: the gripping part is used to hold the entire suture guide during use; the bone channel guiding docking mechanism can guide the docking of the first and second bone channels, thereby facilitating subsequent threading; the pushing mechanism can intermittently push the suture assembly out of the second bone channel. Because of this suture guide, when threading, it is only necessary to insert the suture into the first bone channel. As long as the second bone channel is connected to the first bone channel, the threading can be completed. This solves the problem that existing suture guides can only guide sutures through parallel bone holes, thus improving its applicability.
[0007] Preferably, the gripping part includes: a first handle connected to the upper end of the tube for gripping the entire lead wire; and a second handle movably hinged to the tube, with its inner end disposed inside the tube and connected to the pushing mechanism.
[0008] By adopting the above technical solution, the first handle and the second handle are easy to hold. Since the second handle is hinged to the threading tube, when the second handle is repeatedly squeezed, the second handle can also drive the pushing mechanism to perform threading.
[0009] Preferably, the lead assembly includes a lead wire and a fixing wire, with the end of the fixing wire fixed to one end of the lead wire.
[0010] By adopting the above technical solution: the threading wire is similar to a soft thread with a certain degree of rigidity, and the fixing wire is fixed at the end of the threading wire. When threading, the threading wire can drive the fixing wire through the second bone channel, thereby completing the threading.
[0011] Preferably, the bone channel guiding docking mechanism includes an elastic docking component disposed at the lower end of the bone channel tube and a guiding and limiting component disposed inside the bone channel tube.
[0012] By adopting the above technical solution, the elastic docking component can dock with the first and second bone channels, and the guiding and limiting component can limit and guide the threading wire, which facilitates threading.
[0013] Preferably, the elastic docking assembly includes a connecting plate connected to the lower end of the bone channel tube via a connecting column. The lower end of the connecting plate is provided with a guide head, and the side of the connecting plate is provided with a plurality of elastic arc covers. The upper part of the connecting plate is provided with guide plates corresponding one-to-one with the elastic arc covers.
[0014] By adopting the above technical solution: when the bone tube is inserted into the first bone channel, the elastic arc cover contracts under pressure. When it reaches the connection point with the second bone channel, the elastic arc cover resets to connect the first and second bone channels. Its arc shape serves as a guide for the threading wire. When the bone tube passes through the first bone channel to the connection point with the second bone channel, the corresponding elastic arc cover springs open because it is no longer restricted by the bone hole in the first bone channel, connecting the first and second bone channels. Simultaneously, the guide piece connected to the elastic arc cover swings, guiding the threading wire into the corresponding elastic arc cover. The guide piece can be a semi-cylindrical structure, facilitating the later sliding of the threading wire through the elastic arc cover into the second bone channel. The elastic arc cover and the guide piece are an integral structure, with its middle section hinged to the side of the connecting plate.
[0015] Preferably, the guiding and limiting assembly includes an annular limiting platform disposed inside the bone channel, and the annular limiting platform has a threading channel in the middle for threading the threading wire.
[0016] By adopting the above technical solution: the threading wire guides the fixing wire through the threading channel, so that the threading channel guides the threading wire. The pushing mechanism can gradually push the threading wire out of the second bone channel to complete the threading.
[0017] Preferably, the pushing mechanism includes a sliding component that slides inside the bone channel, a clamping component disposed on the sliding component, and a pushing component that pushes the sliding component to slide.
[0018] By adopting the above technical solution, the sliding component can achieve directional sliding, the clamping component can intermittently clamp the threading wire, and the pushing component can reciprocate to push the threading wire.
[0019] Preferably, the sliding assembly includes a slide rail disposed inside the bone channel tube and a slider slidably disposed on the slide rail, wherein the slide rail is located above the annular limiting platform.
[0020] Preferably, the clamping assembly includes a mounting rod disposed on the slider, and a clamping member for clamping the threaded wire is hinged to the mounting rod via a torsion shaft.
[0021] Preferably, the clamping member includes a hinge portion that is hinged to the mounting rod, the upper part of the hinge portion is provided with a pushing portion, and the lower part of the hinge portion is provided with a clamping portion for clamping the threaded wire.
[0022] By adopting the above technical solution: since the hinge part is hinged to the mounting rod through the torsion shaft, the entire clamping part has an automatic reset function. When the pushing component moves downward, it contacts the pushing part, and the pushing part rotates around the hinge shaft, so that the two clamping parts come closer to each other and clamp the threading wire. When the pushing component continues to move downward, it can push the slider downward, thereby driving the threading wire to move downward. By repeatedly pinching the second handle, the threading wire can be intermittently pushed downward, thereby driving the fixing wire to intermittently pass through the second bone channel and complete the threading.
[0023] Preferably, the pushing assembly includes a pushing tube disposed inside the perforation tube and the bone passage tube, the upper end of the pushing tube being hinged to the end of the second handle located inside the perforation tube, the guiding wire being inserted inside the pushing tube, and an L-shaped lifting rod being provided on the pushing tube, the lower end of the L-shaped lifting rod being located inside a ring disposed on the slider and having a lifting block at its lower end.
[0024] By adopting the above technical solution: a return spring is provided between the second handle and the first handle. When the second handle is squeezed and then released, the return spring can reset the second handle. When the second handle is squeezed, it moves closer to the first handle. The end of the second handle inside the tube moves downward, thereby causing the push tube to move downward. During the downward movement of the push tube, the line contacts the push part and gets close to the mounting rod, thereby causing the clamping part to clamp the threading wire. As the push tube continues to move downward, it can push the slider to move downward along the slide rail, thereby driving the threading wire and the fixing wire to move downward. When the second handle is released, the push tube moves upward. First, the clamping part releases the clamping of the threading wire. Then, the lifting block drives the ring sleeve to reset, thereby resetting the slider, waiting for the next clamping of the threading wire to proceed with the threading process on the next side. Repeating the above operation can thread the threading wire out of the second bone channel, thereby driving the threading wire to drive the fixing wire out of the second bone channel, completing the threading process.
[0025] A second aspect of this application provides a method of using the aforementioned bone channel guide device, comprising the following steps: Fix the end of the fixing wire to the lower end of the threading wire, insert the threading wire into the push tube, insert the bone channel tube into the first bone channel, and when it is inserted to the junction with the second bone channel, the bone channel guiding docking mechanism docks with the first bone channel and the second bone channel. Repeatedly hold the second handle and push the threading wire with the fixing wire out of the second bone channel through the pushing mechanism to complete the threading.
[0026] By adopting the above technical solution, the suture operation is convenient, and sutures can be threaded through asymmetrical bone holes, thus improving its applicability.
[0027] The working principle and beneficial effects of this application are as follows: 1. The gripping part is used to hold the entire suture guide during use. The bone channel guiding docking mechanism can guide the docking of the first and second bone channels, which facilitates subsequent threading. The pushing mechanism can intermittently push the suture assembly out of the second bone channel. Because of this suture guide, when threading, it is only necessary to insert the suture into the first bone channel. As long as the second bone channel is connected to the first bone channel, the threading can be completed. This solves the problem that existing suture guides can only guide sutures through parallel bone holes, thus improving its applicability.
[0028] 2. When the bone tube is inserted into the first bone channel, the elastic arc cover contracts under pressure. When it reaches the connection point with the second bone channel, the elastic arc cover resets to connect the first and second bone channels. Its arc shape serves as a guide for threading the wire. When the bone tube passes through the first bone channel to the connection point with the second bone channel, the corresponding elastic arc cover springs open because it is no longer restricted by the bone hole of the first bone channel, connecting the first and second bone channels. At the same time, the guide plate connected to the elastic arc cover also swings. The guide plate can be a semi-cylindrical structure to facilitate the later guidance of the threading wire to slide through the elastic arc cover and enter the second bone channel. The elastic arc cover and the guide plate are an integral structure, and the middle part can be hinged to the side of the connecting plate.
[0029] 3. Since the hinge is hinged to the mounting rod via a torsion shaft, the entire clamping component has an automatic reset function. When the pushing component moves downward, it contacts the pushing part, which rotates around the hinge shaft, causing the two clamping parts to come closer together and clamp the threading wire. When the pushing component continues to move downward, it can push the slider downward, thereby driving the threading wire downward. By repeatedly squeezing the second handle, the threading wire can be intermittently pushed downward, thereby driving the fixing wire to intermittently pass through the second bone channel, completing the threading.
[0030] 4. In this application, a return spring is provided between the second handle and the first handle. When the second handle is squeezed and then released, the return spring can reset the second handle. When the second handle is squeezed, it moves closer to the first handle. The end of the second handle inside the tube moves downward, causing the push tube to move downward. During the downward movement of the push tube, the line contacts the push part and gets close to the mounting rod, causing the clamping part to clamp the threading wire. As the push tube continues to move downward, it can push the slider to move downward along the slide rail, thereby driving the threading wire and the fixing wire to move downward. When the second handle is released, the push tube moves upward. First, the clamping part releases the clamping of the threading wire. Then, the lifting block drives the ring sleeve to reset, thereby resetting the slider, waiting for the next clamping of the threading wire to proceed with the threading process on the next side. Repeating the above operation can thread the threading wire out of the second bone channel, thereby driving the threading wire to drive the fixing wire out of the second bone channel, completing the threading process.

Detailed Implementation
[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0035] like Figures 1-5 As shown in the figure, this embodiment presents a bone tunnel guide and its usage method, which can be applied to threading various asymmetrical bone holes, and the threading is made more convenient by positioning and pushing.
[0036] Therefore, the technical solution adopted in this application is as follows: a bone channel guide includes a gripping part 100 for gripping the entire guide, and a through tube 200 installed on the gripping part 100 for threading the guide assembly 300; a bone channel tube 400 connected to the lower end of the through tube 200 for threading the guide into a first bone channel 500 during guide insertion; a bone channel guiding and docking mechanism 600 disposed at the lower end of the bone channel tube 400 for automatically docking with a second bone channel 700 after the bone channel tube 400 enters the first bone channel 500; and a pushing mechanism 800 disposed at the lower end of the bone channel tube 400 for pushing the guide assembly 300 to push the guide out of the second bone channel 700.
[0037] The basic principle of this embodiment is as follows: the gripping part 100 is used to hold the entire suture guide during use. By setting the bone channel guiding docking mechanism 600, the first bone channel 500 and the second bone channel 700 can be guided to dock, which facilitates subsequent threading. By setting the pushing mechanism 800, the suture guide assembly 300 can be intermittently pushed out of the second bone channel 700. Because of this suture guide, when threading, it is only necessary to insert it into the first bone channel 500. As long as the second bone channel 700 is connected to the first bone channel 500, the threading can be completed. This solves the problem that the existing suture guide can only guide the suture to parallel bone holes, thus improving its applicability.
[0038] Reference Figures 1-2 In this embodiment, the gripping part 100 includes: a first handle 110, which is connected to the upper end of the tube 200 and is used to grip the entire lead wire; and a second handle 120, which is movably hinged to the tube 200, with its inner end located inside the tube 200 and connected to the pushing mechanism 800. A return spring 130 is provided between the first handle 110 and the second handle 120 for easy gripping. Since the second handle 120 is movably hinged to the tube 200, when the second handle 120 is repeatedly squeezed, the second handle 120 can also drive the pushing mechanism to perform wire threading. When the second handle 120 is released, the second handle 120 can be reset under the action of the return spring 130.
[0039] Reference Figures 3-5 In this embodiment, the lead wire assembly 300 includes a threading wire 310 and a fixing wire 320. The end of the fixing wire 320 is fixed to one end of the threading wire 310. The threading wire 310 is similar to a soft wire with a certain stiffness. The fixing wire 320 is fixed to the end of the threading wire 310. When threading, the threading wire 310 can drive the fixing wire 320 through the second bone channel 700, thereby completing the lead wire connection.
[0040] Reference Figure 4 The main feature is that the bone channel guiding docking mechanism 600 in this embodiment includes an elastic docking component disposed at the lower end of the bone channel tube 400 and a guiding and limiting component disposed inside the bone channel tube 400. The elastic docking component can dock with the first bone channel 500 and the second bone channel 700, and the guiding and limiting component can limit and guide the threading wire 310 to facilitate threading.
[0041] Reference Figure 4 The elastic docking assembly includes a connecting plate 620 connected to the lower end of the bone tube 400 via a connecting post 610. The lower end of the connecting plate 620 is provided with a guide head 630. The side of the connecting plate 620 is provided with a plurality of elastic arc cover bodies 640. The upper part of the connecting plate 620 is provided with guide plates corresponding to the elastic arc cover bodies 640.
[0042] When the bone tube 400 is inserted into the first bone channel 500, the elastic arc cover 640 contracts under pressure. When it reaches the connection point with the second bone channel 700, the elastic arc cover 640 resets to connect the first bone channel 500 and the second bone channel 700. It is arc-shaped and can guide the threading wire 310. When the bone tube 400 passes through the first bone channel 500 to the connection point with the second bone channel 700, the corresponding elastic arc cover 640 springs open because it is no longer restricted by the bone hole of the first bone channel 500, and connects the first bone channel 500 and the second bone channel 700. At the same time, the guide piece 650 connected to the elastic arc cover 640 also swings. The guide piece 650 can be a semi-cylindrical structure to facilitate the later guidance of the threading wire 310 to slide through the elastic arc cover 640 and enter the second bone channel 700. The elastic arc cover 640 and the guide piece 650 are an integral structure, and the middle part can be hinged to the side of the connecting plate 620.
[0043] Reference Figure 4 The guiding and limiting component includes an annular limiting platform 660 disposed inside the bone channel tube 400. The annular limiting platform 660 has a guiding channel 670 in the middle for threading the threading wire 310. The threading wire 310, carrying the fixing wire 320, passes through the guiding channel 670, so that the guiding channel 670 guides the threading wire 310. The guiding mechanism can gradually push the threading wire 310 out of the second bone channel 700 to complete the suture.
[0044] Reference Figure 5 In this embodiment, the pushing mechanism 800 includes a sliding component that slides inside the bone channel tube 400, a clamping component disposed on the sliding component, and a pushing component that pushes the sliding component to slide. The sliding component can achieve directional sliding, and the clamping component can intermittently clamp the threading wire 310, which facilitates the pushing component to reciprocate and push the threading wire 310.
[0045] The sliding component includes a slide rail 810 disposed inside the bone channel tube 400 and a slider 811 slidably disposed on the slide rail 810, wherein the slide rail 810 is located above the annular limiting platform 660.
[0046] The clamping assembly includes a mounting rod 820 on the slider 811, and a clamping member for clamping the threading wire 310 is hinged to the mounting rod 820 via a torsion shaft 821.
[0047] The clamping component includes a hinge portion 822 that is hinged to the mounting rod 820. The upper part of the hinge portion 822 is provided with a pushing portion 823, and the lower part of the hinge portion 822 is provided with a clamping portion 824 for clamping the threading wire 310.
[0048] Since the hinge part 822 is hinged to the mounting rod 820 via the torsion shaft 821, the entire clamping component has an automatic reset function. When the pushing component moves downward, it contacts the pushing part 823, and the pushing part 823 rotates around the hinge shaft, thereby causing the two clamping parts 824 to come closer to each other and clamp the threading wire 310. When the pushing component continues to move downward, it can push the slider 811 downward, thereby driving the threading wire 310 to move downward. By repeatedly pinching the second handle 120, the threading wire 310 can be intermittently pushed downward, thereby driving the fixing wire to intermittently pass through the second bone channel 700 and completing the threading.
[0049] Reference Figure 5 The pushing component includes a pushing tube 830 disposed inside the through tube 200 and the bone passage tube 400. The upper end of the pushing tube 830 is hinged to the end of the second handle 120 inside the through tube 200. The threading wire 310 passes through the inside of the pushing tube 830. The pushing tube 830 is provided with an L-shaped lifting rod 831. The lower end of the L-shaped lifting rod 831 is located in the ring 832 disposed on the slider 811 and its lower end is provided with a lifting block 833.
[0050] A return spring 130 is provided between the second handle 120 and the first handle 110. When the second handle 120 is squeezed and then released, the return spring 130 can reset the second handle 120. When the second handle 120 is squeezed, it moves closer to the first handle 110. The end of the second handle 120 inside the tube 200 moves downward, thereby causing the push tube 830 to move downward. During the downward movement of the push tube 830, it comes into contact with the push part 823 and comes close to the mounting rod 820, thereby causing the clamping part 824 to clamp the threading wire 310. The push tube 830 continues to move downward. In the middle, the slider 811 can be pushed to move downward along the slide rail 810, thereby driving the threading wire 310 and the fixing wire 320 to move downward. When the second handle 120 is released, the push tube 830 moves upward. First, the clamping part 824 releases the clamp on the threading wire 310. Then, the lifting block 833 drives the driving ring 832 to reset, thereby making the slider 811 reset, waiting for the next clamping of the threading wire 310 to carry out the threading process on the next side. Repeating the above operation can push the threading wire 310 out of the second bone channel 700, thereby the threading wire 310 drives the fixing wire 320 out of the second bone channel 700, completing the threading.
[0051] The second aspect of this embodiment provides a method of using the above-mentioned bone channel guide device, including the following steps: The end of the fixing wire 320 is fixed to the lower end of the threading wire 310. The threading wire 310 is inserted into the push tube 830. The bone channel tube 400 is inserted into the first bone channel 500. When it is inserted to the junction with the second bone channel 700, the bone channel guiding docking mechanism 600 docks with the first bone channel 500 and the second bone channel 700. By repeatedly holding the second handle 120, the threading wire 310 with the fixing wire 320 is pushed out of the second bone channel 700 through the pushing mechanism 800, thus completing the wire insertion.
[0052] By adopting the above technical solution, the suture operation is convenient, and sutures can be threaded through asymmetrical bone holes, thus improving its applicability.
[0053] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
